When I travel back to places which hold great significance in my formative years; funny things happen to the perception of time. Years pass in between the morning and evening of a long hiking day. Packing up for a camping trip was a lifetime ago. Memories from my childhood and teenage years, however, are not yet passed. Sometimes I can catch a glimpse of seven year old Seth walking down the trail.
Current time is already a memory while long passed moments are still happening.
